BALING-PRESS.

To all whom it may concern:

Be it known that I, ABIJAH B. BENNETT, a citizen of the United States, residing at ()pelika, in the county of Lee and State of Alabama, have invented certain new and useful Improvements in Baling-Presses, of which the following is a specification.

This invention relates to an improvement in baling presses for hay or similar material.

The invention relates more particularly to a press of this character which is power operated and one of the objects of the pres ent invention is the provision of a simple and efiieient mechanism for operating the press plunger by motive power.

A further object of the present invention is the provision in a press of this character of a baling chamber provided with improved means for preventing the withdrawal of any of the material in the baling chamber as the plunger is retracted.

A still further object of the invention is the provision of an improved construction at the discharge end of the baling chamber.

Further objects of the invention will be apparent from the detailed deseriptionhereinafter when read in connection with the accompanying drawings forming a part hereof, wherein a convenient embodiment of the invention is illustrated and wherein like numerals of reference refer to similar parts in the several views.

In the drawings :-Figure 1 is a side elevation of a baling press constructed in accordance with the present invention; Fig. 2 is a longitudinal section of the same, parts being shown in elevation. Fig. 3 is a top plan view of the baling press. Fig. 4 is a horizontal section thereof. Fig. 5 is a cross section on line 55 of Fig. 2. Fig. 6 is a cross section on line 6--6 of Fig. 2. Fig. 7

' is a front elevation of the baling press, and

Fig. 8 is a detailed view.

Referring now more particularly to the drawings, A A designate a pair of connected longitudinally extending sills which constitute the base of the press and from which extend upwardly a plurality of uprights B which serve to support the baling chamber C of the press.

The baling chamber C of the press comprises a top plate C and a bottom plate G the outer ends of which project beyond the uprights at the outer ends of the supporting base of the press, and suitable side Specification of Letters Patent.

plates C which are supported by the uprights extending from the base of the press.

The top plate C terminates short of the inner end of the baling chamber C so as to provide an opening through which the ma terial may be fed into such baling chamber. The top and bottom plates of the baling chamber are secured in the frame in such a manner that the space between the same at their outer ends is slightly less than at their inner ends.

Pivotally connected to the uprights extending from the outer end of the supporting base of the press so as to form substan tial continuations of the side walls of the baling chamber C, are outwardly extending gates D which cooperate with the projecting portions of the top and bottom plates of the baling chamber to provide a contracted discharge from said baling chamber. Means are provided for exerting pressure against the gates D to cause the same to frictionally engage the bale as it is moved from the baling chamber, such means being yieldable to permit of the discharge of the bale and the usual follower plates. In the present embodiment of the invention the means employed for this purpose comprises a U- shaped frame of metal E, the arms of which are adapted respectively to overlie the upper surface of the projecting portion of the top plate of the baling press and to underlie the undersurfaee of the bottom plate of the baling press. Loosely mounted upon the frame is a bar E which is provided with suitable openings in the end portions there of to engage the arms of the frame and which is adapted to lie against the base of said frame.

E E designate a pair of bars, each of which is provided with openings in the end portions thereof which loosely receive the arms of the frame E. .The bars E are adapted to lie one upon each side of the projecting portion of the baling chamber C and are provided on the inner sides thereof with inwardly projecting portions 6 which are adapted to engage the outer surfaces of the doors D.

Encircling the arms of the frame E and positioned between one of the bars E and the bar E are a pair of coil springs 6. Threaded upon the projecting ends of the arms of the frame E are hand wheels 6 From the above described construction it will be seen that by adjusting the hand wheels 6 the doors D may be moved inwardly to any desired extent and that at the same time they are free to yield in an outward direction as the bale passes therebetween. By reason of the formation of the inwardly projecting portions 0 on the inner surfaces of the bars E it will be seen that the doors D may be adjusted inwardly for a substantial distance beyond the planes of the outer edges of the top and bottom plates of the baling chamber.

T 0 prevent material in the baling chamber from working rearwardly therein, as the plunger is withdrawn, suitable stop members are provided in the side walls C of the baling chamber. In the present instance two such stop members are provided in each side wall of the baling chamber, said side walls being each provided with a pair of longitudinally extending slots 0 extending therethrough in each of which is pivotally secured a stop member F. Each of the stop members F is angular in shape so as not to interfere with the inward movement of the plunger and is pivoted at its small end in one of the slots 0, above referred to, so as to work freely therein. The outer edge of each of the stops F is provided with a laterally extending portion f which is adapted to contact with the side wall of the baling chamber to limit the inward movement of the stop and to prevent the same from moving too far into the baling chamber.

Positioned upon the exterior of each of the side walls C of the baling chamber C of the press is a vertically disposed leaf spring F, the ends of which lie upon the outer edges of the two stop members F which are supported by said side wall and tend to hold the same in a position projecting into the baling chamber of the press. The leaf spring F is carried by a bar F which may be adjusted longitudinally of the side wall of the press. In the present embodiment of the invention, I have shown the bar F as provided with a longitudinal slot f which loosely engages a bolt f which projects from the side wall of the baling chamber. A wing nut f threaded upon the outer end of the bolt f serves to hold the bar F in any position of adjustment. By adjusting the bar I it will be seen that the spring F carried thereby will be also shifted so that the points of engagement of such spring with the stop members will also be shifted. By shifting the spring in this manner, it is possible to hold the stop members under any desired degree of tension.

In addition to the stop members F above described, I prefer to use at the upper portion of the inlet end of the baling chamber atucker bar, the function of which is to prevent any material from working back out of the baling chamber at this point.

The tucker just referred to comprises a bar G provided with a beveled lower edge and with extensions 9 extending from the ends thereof, which work in suitable guides g formed in the frame of the press adjacent the front ends of the top plate of the baling chamber. hen the tucker is in its lowermost position, the lower edge thereof will be so positioned as to just permit the plunger to clear the same as it moves into the operating chamber. Movement of the tucker bar in the guides g is resisted by a bowed leaf spring G the ends of which rest directly upon the upper surface of said tucker bar.

Secured to any suitable portion of the frame of the press and overlying the bowed sprin G is a bracket G in which is threaded a screw G the lower end of which is adapted to engage the top of the bowed spring Gr. Obviously by adjusting the screw Gr just referred to the pressure ex" erted by the spring G on the tucker block G may be regulated to any desired extent.

H designates a plunger which is adapted to work within the baling chamber C. Extending rearwardly from the plunger H is a projection H in which is journaled in any suitable manner, a roller H which is adapted during the reciprocation of the plunger to travel on the bottom plate C of the baling chamber.

Extending upwardly from the inner end of the base of the press and positioned between the side walls A A thereof is a standard I from the upper end of which extends two brace members I, the inner ends of which are rigidly connected in any suitable manner to the sides of the upright I and the forward ends of which are rigidly connected to the front portion of the baling chamber of the press or to any other suitable portion of the frame thereof.

Journaled in suitable bearings carried by the sills A A is a shaft K to one end of which is secured a suitable driving pulley and to the other end of which is secured a balance wheel. Carried by the shaft K is a small pinion K which meshes with a larger pinion K which is mounted on a stub shaft K journaled in a suitable bearing secured to one of the supporting sills A of the press. 7

L designates an elongated link one end of which is loosely connected to a suitable crank projecting from the pinion K and the upper end of which is pivotally connected to the free end of a relatively short link L, the rear end of which is pivotally cognected to the upper end of the standar I.

M designates a pitman one end of which is pivotally connected to the projection H extending from the rear side of the plunger J and the other end of which is pivotally connected to the link L below the point of connection between said link and the link L.

When the plunger K is in its retracted position, the link L projects upwardly from the standard I in a substantially vertical position. As the shaft K is rotated, however, the rotation of the larger pinion K will through the link L draw the link L downwardly to a substantially horizontal position, and the pitman M will be shifted to cause the plunger to enter the baling chamber and compress the material which has been previously fed thereinto. By reason of the fact that the pitman M is connected to the link L below the point of connection of such link with the link L, itwill be seen that a direct thrust is applied to the plunger during the operation of the device.

With power driven presses of this character difficulty has been experienced by reason of the breaking or straining of parts of the operating mechanism should the plunger be actuated when there is no charge in the baling chamber, and in the present invention I have sought to obviate this objection by providing means for preventing the operating mechanism from being subjected to any such strains even though it should be actuatedwhen the baling chamber of the press is empty. In the present embodiment of the invention such means comprises a leaf spring N which is rigidly secured to the standard I and projects upwardly therefrom. The leaf spring N has rigidly secured to the upper end thereof a cross bar a to the extremities of which are pivotally connected the upper ends of a pair of downwardly extending links n. Pivotally secured to the lower end of the links a are a pair of links M, the free ends of which are pivotally connected to the link L. The combined lengths of the links n and n is such that during the major portion of the downward movement of the link L the spring N will not be brought into action. Just before the link L reaches the limit of its downward movement, however, the links n and n will have been moved into alinement so as to form a direct connection between the link L and the spring N. During the remainder of the downward movement of the link L the spring N will be placed under tension so as to resist the movement of the plunger H during the extreme outer portion of its travel in the baling press.

From the above described construction it will be seen that the spring does not in any way interfere with the movement of the operating mechanism except during the extreme outer portion of the travel of the plunger when it is automatically brought into play to prevent any injury to the operating mechanism.

While I have illustrated a convenient embodiment of the invention in the drawings,

it will be obvious that many changes may be made to the form and construction therein shown without departing from the spirit and scope of the invention as defined in the appended claims.
